A source file defines one of these macros to declare that it uses features of that standard as opposed to conflicting features of other standards (e.g. the POSIX foo() subroutine might do something different from the X/Open foo() subroutine). Plus, this forces the coder to understand upon what feature sets his program relies. But some C library developers have misunderstood this and think of these macros like the old __ansi__ macro, which tells the C library, "Don't have any features that aren't in the ANSI standard." I.e. it's just the opposite -- the macro subtracts features instead of adding them. This means that on some platforms, Netpbm programs must define _POSIX_SOURCE, and on others, it must not. Netpbm's POSIX_IS_IMPLIED macro indicates that we're on a platform where we need not define _POSIX_SOURCE (and probably must not).
